Re: 2001 Allison 5-spd Auto maintenance question
Thx Hatzie, appreciate the input. I may go with the following based on what I've seen so far:
- spin-on (only, without pan drain) every 12.5K
- spin-on (with pan drain) every 25K
- spin-on, pan drain, and internal trans filter every 50K per the manual
With the 25K service, I'll check the fluid to see how it looks, and maybe skip this in the future, it is still likely overkill.
Thanks again!
